Seismic intensity information providing device and seismic intensity information providing method

摘要

PROBLEM TO BE SOLVED: To allow a user to grasp a measured seismic intensity at a desired location.SOLUTION: A seismic intensity information providing device of the present invention comprises: a storage unit for storing a plurality of tile image files; a database comprising an earthquake information table for storing storage locations of earthquake ID classification codes, earthquake basic data and the tile image files, an estimated seismic intensity distribution table for storing the earthquake ID classification codes, measured seismic intensities, and data indicating zones in which the measured seismic intensities are estimated, and an observation point seismic intensity table for storing the earthquake ID classification codes, the measured seismic intensities and data indicating observation points of the measured seismic intensities; a tile image file generation unit for generating the plurality of tile image files and expanding the same in the storage unit when the estimated seismic intensity distribution table or the observation point seismic intensity table has been updated; an earthquake search unit for outputting data indicating a storage position and an earthquake ID classification code; and a seismic intensity search unit for outputting data indicating a measured seismic intensity and an earthquake ID classification code.SELECTED DRAWING: Figure 1
